Several motherboard components are very close to the cooling assembly. Take care not to 
damage these components when removing or replacing the cooling assembly.

• Move the levers on the clamp to the 

open position (spine up).

• Use a small flathead screwdriver to 

bend the four hooks out of the slots 
in the bracket one at a time. Make 
sure not to damage the motherboard 
as you bend the hooks out of the 
bracket.

• Lift the cooling assembly off the CPU 

socket and set it aside.
Use caution when lifting the cooling 
assembly out of the bracket. The 
thermal compound applied to the 
bottom of the heatsink may damage 
the CPU if the heatsink is removed 
too forcefully.

Two flexible metal clips secure the cooling 
assembly to a plastic retention bracket 
surrounding the CPU socket.

• To remove a clip, press down on the 

thumb pad to relieve the clip’s tension 
and then carefully move the clip arm 
to disengage it from the slot in the 
bracket.

• Disengage the other clip arm from the 

other slot in the bracket.

• Repeat this procedure to remove the 

other clip.

• Carefully lift the cooling assembly off 

the CPU socket and set it aside.

Use caution when lifting the cooling 
assembly out of the bracket. The 
thermal compound applied to the 
bottom of the heatsink may damage 
the CPU if the heatsink is removed 
too forcefully.

You should not need to remove the 

fan from the heatsink. Replacement 
cooling assemblies ship with the fan 
already attached.

• For the Type A cooling assembly, see the instructions below.

• For the Type B cooling assembly, see page 28.

• Make sure the levers on the

clamp are in the open position (spine 
up).

• Align the heatsink so that the 

fan cable is near the CPU fan 
connector on the motherboard 
(FAN1). 

• Place the heatsink on the CPU and 

inside the bracket. 

Make sure the heatsink is fully seated 
in the bracket on all 
sides.

• Press down on the clamp until all four 

hooks engage the slots in the bracket. 

Avoid using excessive force when 
pressing down on the clamp. 

• Close the levers simultaneously.

Closing the levers simultaneously 
applies clamping force equally over 
the CPU and bracket.

• Make sure the fan is securely attached 

to the top of the heatsink. 

In most cases, the fan is already 

attached to the heatsink. 

• Align the heatsink so that the fan 

cable is near the CPU fan connector 
(P1 FAN1) on the motherboard. 

• Place the heatsink on the CPU and 

inside the bracket. 

Make sure the heatsink is fully seated 
in the bracket on all sides.

• Insert the hook of the stationary clip 

arm into a bracket slot.

• Allow the clip to lay across the groove 

in the top of the heatsink.

• Hook the movable clip arm into the 

bracket slot on the other side of the 
heatsink. 

• Orient the other clip in the opposite 

direction and then install by repeating 
the previous step. The “opposite” 
orientation helps apply clamping 
force equally over the heatsink.

Avoid using excessive force when 
pressing down on the thumb tabs.
